Hello, I've recently run into a problem with the RC transmitter for my X8+ (TH9X). The copter flies fine (after a recent ESC and accelerometer re-calibration) but I am not getting any battery readings on the transmitter. All the battery readings have been at or near zero (distance and altitude seem ok). This problem has persisted through several flights, disconnects/reconnects and with two different batteries: the Turnigy 10,000 mAh that came with the copter and this Maxamps battery. It's an 11,000mAh, 4c battery, almost brand new.

Any ideas on how to fix this?
